How are atoms often represented?

Answer 1

The symbols of the elements and subscripts are used to represent a molecule of an element or a compound.

N2, O2, H2, Cl2, Br2, I2, F2, At2 are diatomic molecules of the element in each formula.

C6H12O6, NO2, H2O, CO2 are examples of molecular compounds.

NaCl, MgSO4, CaCl2 are examples of ionic compounds.

Answer 2

What you need is simply the molecule's 'formula'.

For methane, for example, you'd write CH(4) (subscript on the 4). This shows there are one carbon and four hydrogen atoms present in each single methane molecule.

If what you seek is a visual representation of molecules and what parts make them up, there are a variety of models: stick-and-colored ball, closely-packed colored balls, and more exotic models that try to give more realistic depictions of where the electrons are (the outermost parts of each atom, which get shared between them and effectively bond the atoms together in most molecules).
